  • the extension portion 150 ′ extends outwards in the third direction D 3 (i.e., +Y-axis direction) from the first holding portion 110 ′, the heating portion 180 is partially or completely embedded in the first holding portion 110 ′ and the extension portion 150 so as to generate a high-temperature distribution along the first holding portion 110 ′ and the extension portion 150 .
  • step S 101 as the dismantling device 1 ′ is installed on the frame 96 (step S 101 ), the first holding portion 110 ′ and the second holding portion 120 ′ together clamp the frame 96 (step S 103 ), and the heating portion 180 heats and soften the adhesive between the frame 96 and the laminated structure 90 (step S 104 ), then the step S 105 ′ and step S 107 ′ can be performed.
  • step S 105 ′ the lever 190 is disposed through the through hole 121 of the second holding portion 120 ′ and presses against the outer wall 9602 of the frame 96 , then or meanwhile, in step S 107 ′, the lever 190 is forced to move with respect to the laminated structure 90 while taking its end as a fulcrum, gradually peeling the frame 96 off from the edge of the laminated structure 90 .
  • one end of the lever 190 is disposed through the through hole 121 at the end of the second holding portion 120 ′ and presses against the outer wall 9602 of the first side frame part 961 , then or meanwhile, the lever 190 is rotated away from the outer wall 9602 (e.g., the direction of arrow A 1 ), such that the dismantling device 1 ′ is forced to rotate with respect to the laminated structure 90 about the end that the lever 190 presses against the outer wall 9602 , thereby forcing part of the first side frame part 961 to gradually move away from the edge of the laminated structure 90 .
  • the rest part of the first side frame part 961 can be peeled off from the laminated structure 90 by repeating the above steps, and the other first side frame part 961 and second side frame parts 962 can be removed by the same approach.
  • a dismantling device 1 ′′ is provided, but for the purpose of simple illustration, only the differences between the previous and following embodiments will be described in detail, the same or similar parts of them will be designated by the same reference numbers and can be understood with reference to the previous paragraphs so will not be repeated hereinafter.
  • the dismantling device 1 ′′ further includes a holding plate 160 extending in the third direction D 3 (i.e., +Y-axis direction) and fixed to the end of the second holding portion 120 ′.
  • the holding plate 160 is movable with the second holding portion 120 ′.
  • the holding plate 160 is configured to be attached to the outer side of the clamping part 960 opposite to the laminated structure 90 so that the clamping part 960 will be located between the holding plate 160 and the laminated structure 90 during the dismantling process.
  • the heating portion 180 is arranged along the holding plate 160 , in specific, the heating portion 180 may be arranged at the side of the holding plate 160 that is used to contact the clamping part 960 .
  • the heating portion 180 can be in thermal contact with the part of the outer wall 9602 of the frame 96 that is close to the clamping part 960 , that is, the heating portion 180 can be very close to the adhesive between the clamping part 960 and the laminated structure 90 so as to be more effectively soften the adhesive.
  • the heating portion 180 is optional and not intended to limit the disclosure.
  • the dismantling device may omit the heating portion 180 , in such a case, the dismantling device may also omit the extension portion.
  • the aforementioned dismantling devices can be operated manually or operated automatically by cooperating with automotive apparatus.
  • the second holding portion is movable close to or away from the first holding portion so as to clamp and deform the frame together with the first holding portion, which allows user to gradually peel the frame off from the PV module by simply pulling, pushing, and/or rotating the dismantling device while largely preserving the integrity of the laminated structure.
  • the dismantling device as discussed in the above embodiments of the disclosure can separate frame from module without further damaging the internal components, achieving higher recovery/recycling rate and improving the quality of recovered materials.
  • the dismantling device may further include a pushing portion extending from the extension portion and used to press against the outer wall of the frame while the first holding portion and the second holding portion clamping the frame, thus while the connection portion, the first holding portion and/or the second holding portion is forced to push or pull the frame, the dismantling device can be rotated as a lever with the pushing portion acting as a fulcrum to gradually peel the frame from the edge of the laminated structure.
  • the dismantling device may further include a lever that can be disposed through the through hole at the end of the second holding portion and to press against the outer wall of the frame, thus the dismantling device can be rotated by taking the end of the lever as a fulcrum to gradually peel the frame from the edge of the laminated structure.
  • the dismantling device may further include a heating portion arranged along the extension portion to create a high-temperature distribution along the extension portion to reduce or remove the stickiness of the adhesive between the frame and the laminated structure before the removal of the frame, and thereby reducing the force needed to peel the frame from the laminated structure and preventing the force for removing the frame from being too large to damage the laminated structure.
